Energy Study Guide Created by: Hanna Katt and McKenna Zink
Kinetic Energy Kinetic Energy is a form of energy that is in the state of motion. As long as the object is moving, (in any form) it is considered to have kinetic energy involved in it. An example of kinetic energy is when you pass the top of a hill on a rollercoaster, and it is racing with motion down that hill. Since the object (a rollercoaster) is moving downward, it is in a state of motion (so this action has kinetic energy).
Potential Energy Potential energy is a form of energy that is being stored due to its position or configuration. As long as the object is not in any form of motion, it is considered to have Potential Energy. An example of potential energy is when someone is pulling back a bow and arrow (and holds it). As they are holding this position, it is storing energy (so this is Potential Energy).
Mechanical energy is energy associated with the motion or position of the object. Mechanical energy can occur as Kinetic or Potential energy (Prentice Hall textbook).\
An example would be like moving water (s
uch as a river).
Mechanical word usage: Striking the head of a nail with a hammer is an example of mechanical energy
Thermal Energy is the amount of particles in an object. When the energy is increasing, the particles move faster (so it is warmer at touch).
An example is regualer heat (like an oven).
Acoustic energy is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid or gas composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensations stimulated in organs of hearing by such vibrations. http://en.wikipedia.org/wiki/Acoustic_energy
An example would be an instrument (like a drum).
Acoustic word usage: The ceiling stepped down toward the screen to improve acoustics.
Electrical Energy
Electrical energy is the presence and flow of an electric charge. The energy portion of electricity is found in a variety of phenomena such as static electricity, electromagnetic fields and lightning. Humans have found the ability to harness these phenomena and store the electrical charge for later use. The concept of electrical energy is defined using a variety of different terminologies such as charge, current and potential. http://www.wisegeek.com/what-is-electrical-energy.htm
-An example of electric energy is a lightning strike. Electrical word usage: Electrical energy can be used in your home sometimes, such as through out different wires connecting to your appliances.
Chemical Energy
Chemical energy is a form of potential energy related to the structural arrangement of atoms or molecules. This arrangement may be the result of chemical bonds within a molecule or otherwise. Chemical energy of a chemical substance can be transformed to other forms of energy by a chemical reaction. http://www.waterfuelconverters.com/ChemicalEnergy.html
-An example of chemical energy is a match burning. Chemical word usage: The batteries that we use in our electronics, such as cell phones and television remotes, use chemical energy.
Electromagnetic Energy
Electromagnetic radiation (often abbreviated E-M radiation or EMR) is a form of energy exhibiting wave like behavior as it travels through space. EMR has both electric and magnetic field components, which oscillate in phase perpendicular to each other and perpendicular to the direction of energy propagation. http://en.wikipedia.org/wiki/Electromagnetic_energy
-An example of Electromagnetic energy are X-Rays. Electromagnetic word usage: An electromagnetic wave can be found coming out of either a cell phone and/or radio tower.

-Kinetic word usage: Sinking the eight ball in the side pocket will require careful control of the kinetic energy.

An example of potential energy is when someone is pulling back a bow and arrow (and holds it). As they are holding this position, it is storing energy (so this is Potential Energy).
-Potential word usage: The potential energy is greatest at the top of a hill.

Thermal Energy is the amount of particles in an object. When the energy is increasing, the particles move faster (so it is warmer at touch).An example is regualer heat (like an oven).
Thermal word usage: The sum of Kinetic and Potential energy of all the molecules in an object is called thermal energy.

Nuclear Energy
The energy released by a nuclear reaction, especially by fission or fusion. Nuclear energy regarded as a source of power. Also called atomic energy http://www.thefreedictionary.com/nuclear+energyAn example of nuclear energy is the sun.
Nuclear word usage: Nuclear energy produces heat that can be converted into energy by normal power plant methods.

-You should teach kinetic and potential energy by showing them a picture of a bow and arrow and explaining what it means. Then, you should do an actual demonstration in front of the class. After you do that, you should give each student a bow and arrow (so they then can discover when the potential and kinetic energy is occurring). Once they figure it out, the whole class should have a discussion about the answer.
- you should teach thermal energy by having a a oven getting hotter, or having an ice cream cone melting. Then have a discussion about what happened to the oven and the ice cream.
-You should teach acoustic energy by having the teacher do a demonstration of how to play the drum or guitar properly. Then have the students try it themselves. Then after that have a discussion about what happened.
-You should teach electrical energy by blowing up two balloons and rubbing them against carpet for a while then stick the balloons on your hair. Then your hair will stick up and the balloons will stick to your head when you let go of the balloons. After you try that have a discussion about what happened.
-You should teach chemical energy by giving each student a snack. Then talk about what is happening in the stomach.
-You should teach electromagnetic energy by having the teacher either turn on a lamp or light switch and explaining how the energy is entering and extiting the light. Then have a class discussioin about the answer.
-You should teach nuclear energy by showing the students a video showing different examples of it (such as time bombs, power plants, etc). Then hav a class discussion after the video describing what it is and what is happening in each example.
